Etymology: "Inerts" is the plural of "inert", so its history is that of the adjective. The root is Latin "iners", meaning "unskilled", "idle" or "inactive", built from "in-" (not) and "ars" (skill, art). A Latin speaker called someone "iners" who lacked craft or knowledge, and the sense of simply being motionless or doing nothing grew naturally from there. The word reached English through French "inerte", which kept the Latin sense of idleness and lack of motion. In English the physical sense of "unable to move" came to the fore, and it was later applied to chemistry, where an inert substance is one that does not readily react with others. Noble gases such as neon and argon are the classic examples.
